UNlTED STATES ALBERT H. EHRLICI'I, OF ST. JOSEPH, MISSOURI.

DISPLAY REFRIGERATOR.

Application filed November 19, 1925.

rl`his invention relates to an improvement in display refrigerators.

The object of the invention is to arrange for thoroughly cooling the display compartinent of the refrigerator so that. the goods will be kept in a cooled condition while, yet, they are clearly visible for display purposes.

Vil ith this object in view, the ice compartments are so arranged at the rear of the refrigerator' that the brine water which acoumulates and is drained therefrom will be directed through independent gutters to the front ofthe display case where each of these independent gutters discharges into a central gutter extending along the front of the ease and out through the out-let at one end thereof.

ln the accompanying drawings F 1 is a horizontal section through the improved display refrigerator; and

Fig. 2 is a vertical Section through the saine on the line 2 2 of Fig. 1.

The numeral 1 indicates the refrigerator as a whole, which is provided with the usual insulated walls 2 and has a slanting glass front 3, formingl a display compartment d, into which access is gained thereto through the sliding doors 5. Wire shelves 6 are provided in the bottom of the display compartment 4 of the refrigerator for supporting the goods on display at a slight elevation abeve the bottom of the case.

The top rear section of the refrigerator is made substantially flat and horizontal and is provided with removable closure covers 7, which open to admit access to the ice tanks 8, there being a plurality of ice tanks provided in the rear of the refrigerator, as clearly shown in F ig. 1. These ice tanks 8 may be used to contain cracked ice, to which salt is usually added, and for the purpose of draining the salt water or brine from the tanks overflow pipes 9 are provided in *i5 the oblique walls 14, at the front of the tanks 8. These overflow pipes 9 discharge into transverse gutters 10 extending across from the back to the front of the case, where they terminate in a longitudinal gutter 11 "5U extending along and adjacent the front of the refrigerator, as clearly shown in Fig. 1. A trap drain 12 is provided at the outer end of the longitudinal gutter 11, in order to drain the salt water from the refrigerator. .lt will be noted that these gutters 10 and 11 are made and placed in the floor of the Serial No. 70,023.

display refrigerator immediately below and in close proximity to the wire shelves 6.

The purpose of this relation is to insure al perfect cooling of the products on display.

lt will be evident from the foregoin description, when taken in connection witg the drawings, that as ice, which may be either cracked or in the piece and either with or without salt, is placed in the ice tanks 8 through the cover 7, it will melt to a certain extent and it is desirable to drain olf this ice water or brine from the ice tanks.l as fast as it melts. In the present construction, the ice water will drain through the overflow pipes 9 from the tanks 8 into the transverse gut-ters 10, where it will flow transversely across the case immediately below the goods on the display shelves 6 and, since these transverse gutters discharge into the v longitudinal gutter 11, this ice water or brine will flow from the gutters 10 into and through the longitudinal gutter 11 to the drain pipe 12, where it is led from the` case.

Thus, the ice water from the ice tanks is circulated across and along the bottom of the display compartment in close proximity to and immediately below the goods mounted on the display shelves, so that this ice water will keep these goods in a cooled condition, while, yet, they are on display. Since the ice water is led in several streams transversely across the bottom of the case and then longitudinally of the case, it will be evident that this provides a greater amount of circulation of cold ice water through the case than is ordinarily possible. This circulation of ice water in close proximity to the goods keeps such perishable goods in a cooled condition, while they are on display for sale.

I claim:

1. A display refrigerator including a display compartment, means mounted therein for supporting goods on display, an ice tank arranged longitudinally and at the rear of the display compartment, said ice tank having an oblique wall inclined in a direction substantially toward the longitudinal center of the display compartment, a drain pipe connected with said oblique wall, and a gutter into which said drain pipe discharges.

2. A display refrigerator including a display compartment, means mounted on the bottom of said display compartment in close proximity with the :door thereof for supporting goods on display, a plurality of ice tanks arranged longitudinally and at the rear of the display compartment, each of said ice tanks having an oblique Wall inclined in a direction substantially toward the longitudinal center of the display Compartment, a drain pipe connected with the oblique wall of each ice tank, a plurality of transverse gutters extending across the {loor of the display compartment immediately below the supporting' means into which the 10 In testimony whereof I afIiX my signal5 ture.
